Rich Salz 53934822ac Clean up "generic" intro pod files.
Files like dh.pod, etc., mostly duplicated the API-specific pod files.
Removed the duplicated content; that often mean the whole file could
be removed.  Some of the content about internals got moved into README
files in the source tree.  Some content (e.g., err.pod) got moved
into other pod pages.

Annotate generic pages, remove dup NAME

=head1 NAME
x509 - X.509 certificate handling
=head1 SYNOPSIS
#include <openssl/x509.h>
=head1 DESCRIPTION
A X.509 certificate is a structured grouping of information about
an individual, a device, or anything one can imagine. A X.509 CRL
(certificate revocation list) is a tool to help determine if a
certificate is still valid. The exact definition of those can be
found in the X.509 document from ITU-T, or in RFC3280 from PKIX.
In OpenSSL, the type X509 is used to express such a certificate, and
the type X509_CRL is used to express a CRL.
A related structure is a certificate request, defined in PKCS#10 from
RSA Security, Inc, also reflected in RFC2896. In OpenSSL, the type
X509_REQ is used to express such a certificate request.
To handle some complex parts of a certificate, there are the types
X509_NAME (to express a certificate name), X509_ATTRIBUTE (to express
a certificate attributes), X509_EXTENSION (to express a certificate
extension) and a few more.
Finally, there's the supertype X509_INFO, which can contain a CRL, a
certificate and a corresponding private key.
B<X509_>I<...>, B<d2i_X509_>I<...> and B<i2d_X509_>I<...> handle X.509
certificates, with some exceptions, shown below.
B<X509_CRL_>I<...>, B<d2i_X509_CRL_>I<...> and B<i2d_X509_CRL_>I<...>
handle X.509 CRLs.
B<X509_REQ_>I<...>, B<d2i_X509_REQ_>I<...> and B<i2d_X509_REQ_>I<...>
handle PKCS#10 certificate requests.
B<X509_NAME_>I<...> handle certificate names.
B<X509_ATTRIBUTE_>I<...> handle certificate attributes.
B<X509_EXTENSION_>I<...> handle certificate extensions.
